As you may have heard, Apple released the public beta for OS X El Capitan yesterday. Since I tend to ignore the risks of beta software in favor of all the new features, I downloaded it on my mid-2011 MacBook Air. Do yourself a favor: don’t be like me. Understand and acknowledge the risks of beta software. It’ll save you time and data.

OS X Yosemite is packed with new features. Unfortunately, not everybody knows every single trick to squeeze the latest, greatest functionality out of Apple’s new system software.

In today’s instructional Cult of Mac video, we share five basic OS X Yosemite tricks that everyone needs to know. We’ll show you how to make phone calls from your Mac, switch to Yosemite’s “dark mode,” use Spotlight like a pro, easily record video from your iOS device screen, and let other people control your Mac (and vice versa).

Are you one of the many, many OS X Yosemite users who have been plagued with intermittent, seeming unsolvable problems with Wi-Fi dropping since upgrading from Mavericks? The end to your problems may very well be coming down the pipe.
